This device is designed to relay digital signals coming from a switch or a proximity sensor installed in hazardous area to the safe area. Input: Switch or proximity sensor Output: Switch (5A – 250V) or transistor (5kHz) Supply: 24-48 VDC, 110 VAC or 230 VAC Model: 1 or 2 channels and signal duplicator (1 input – 2 outputs) Red LED for relay state, and green LED for presence of voltage Installation : Safe area Options: » Alarm (loop integrity with proximity sensor) » Screw terminals » Icc current limited to 20mA or 5mA according to codification » ACCDIVBX power supply cables » Ex d enclosure - RTPE9-DIN or other Ex d enclosure EC Type examination certificate number : LCIE 02 ATEX 6104X IECEx conformity certificate : LCI 09.0013X ATEX/IECEx classification : II (1) GD [Ex ia] IIC or [Ex ia] IIB or [Ex iaD] The RDN is an intrinsically safe, galvanic-isolated relay for switches or proximity sensors. The RDN supplies the switch in a hazardous area (8.2 V at 8 mA). The relay output (F E) is voltage-free. Green LED to indicate power is supplied to the module. Red LED to indicate activation of the output relay. Red LED (AL) to indicate that the alarm transistor is conductive. It becomes conductive when the proximity sensor (Namur) input is outside of its operating range.
